The Rolex GMT-Master, a watch synonymous with global travel and aviation, boasts a rich and fascinating history. Among its various iterations, the reference 1675 holds a particularly special place in the hearts of collectors. Produced from 1959 to 1980, this model represents a significant chapter in the GMT-Master's evolution, bridging the gap between its early years and the arrival of later, more modern designs. This article will delve into the specifics of the Rolex 1675 GMT-Master, with a particular focus on a 1967 example, highlighting its features, historical context, and the enduring appeal that makes it a coveted piece among watch enthusiasts. The somewhat mysterious "Concorde" moniker, often associated with certain 1675s from this period, will also be examined.
Rolex 1675 GMT-Master: A Technical Overview
The Rolex reference 1675 GMT-Master is instantly recognizable for its robust construction and distinctive features. It houses the legendary Calibre 1575, a robust and reliable automatic movement renowned for its accuracy and longevity. This movement, a workhorse of Rolex engineering, features a 24-hour hand, allowing for the simultaneous tracking of two time zones – a crucial feature for pilots and frequent travelers, the watch's original target demographic. The bidirectional rotating bezel, a hallmark of the GMT-Master line, is graduated in 24 hours, typically with a contrasting color insert (often black or red and blue, commonly known as a "Pepsi" bezel). The bezel allows the user to set a reference time, usually home time, while the main hands and 24-hour hand indicate the local and second time zones respectively.
The case of the 1675 is typically 40mm in diameter, a size considered relatively modest by today's standards but perfectly proportioned for its era. The case material was predominantly stainless steel, contributing to its durability and resilience. While variations exist, the 1675 generally features a screw-down crown and caseback, ensuring water resistance and protecting the movement from the elements. The dial variations are numerous, adding to the complexity and desirability of collecting different examples. From matte dials to glossy dials, and various marker and hand styles, the dial adds significant character to the watch.
Rolex Reference 1675 Bezel: A Key Identifying Feature
The bezel of the Rolex 1675 plays a crucial role in both functionality and aesthetics. As mentioned, it's a bidirectional rotating bezel, allowing for easy adjustment of the 24-hour hand. The material and color of the bezel insert were key differentiating factors across different production years and variations. Early examples often featured Bakelite inserts, known for their rich color and gradual aging patina. Later, they transitioned to aluminum, which offered a different aesthetic and aging characteristic. The color combinations, particularly the red and blue "Pepsi" bezel, are highly sought after by collectors, often commanding premium prices. The condition of the bezel insert, its color retention, and the presence of any fading or scratching significantly impact the value of a 1675.
The insertion of the bezel was a crucial aspect of the watch's production. The method of securing the bezel insert evolved over the years, leading to subtle differences that are examined by collectors to pinpoint the exact production period. A careful examination of the bezel and its relationship with the case can provide clues about the watch's authenticity and age.
